I am working my way through a plugin for OziExplorer a topographical GPS mapping application that has its own interface DLL using C and need to understand a couple of things:
1. Does RR ask the DLL for the label text or does the DLL just send it whenever it likes?
The reason I ask is that Ozi allows me to define a callback routine that receives GPS position data etc. I need to know if I should send this data to RR on receipt or save it in a global variable until asked for it.
2. Does the COM model support setting a label in RR? I could not understand how a label is updated in RR using COM.
Thanks in anticipation
